To speed up cutting in SketchUp for 3D models, simplify your model by removing unnecessary edges, faces, or groups—this reduces the data SketchUp processes during cuts.
Use components instead of copies for repeated elements: SketchUp handles components more efficiently, so cuts happen faster.
Hide or delete hidden geometry (like leftover edges from imports) to lighten the model’s load on cutting tools.
For large models, isolate the section you need to cut with the "Isolate" tool. This focuses SketchUp’s resources on your work area, speeding up cuts without changing the entire model.
